Ok so thought I would do a How to Guide on this, I know to some its easy but others it maybe a help.
Oil Change on a 5.9ltr 1998 Dodge Ram. or Mopar 360 engine.
1) Tools, a Cloth, 15mm or 16mm socket, Rechet, Oil catch tray, New oil, new compression washer.
2) Take your truck for a run operating temp. Best to change oil when its hot.
3) Once at operating temp, switch off engine and pop bonnet, remove oil filler cap and dip stick wipe and put to one side.
4) slide underneath your truck (make sure its safe) take with you oil catch tray, cloth, plus you 15mm or 16mm socket and ratchet, make sure your ratchet is on undo (anti clockwise)
5) locate the sump nut this is a Bolt usually the lowest one on the engine it is in the rear side of the Sump.
6) Attach your 15mm or 16mm socket to ratchet and then onto the sump bolt, Now with one hand holding the ratchet on to the bolt use the other hand on the handle of the ratchet and undo (Sometime you made need to give it a bash)
7) once you have started to undo the Bolt get a cloth and catch tray in position, Now take off the ratchet and socket put the cloth around your hand and fingers and undo the rest of the way untill the sump bolt is removed ( be careful here the oil will be thin black pea water and very HOT)
8) slide out from under truck and leave to drain out. At this point if you was doing filter as well you could swap that out for the new one, these are only hand tight and are near the exhaust headers on the intake side of engine, the filter will be hanging down. Remember to fill the new filter with some new oile before putting it on.
9) Have your self a quick brew while it drains.
10) Get your sump bolt and remove the old copper compression washer off it, wipe the bolt and put the new copper compression washer on.
11) check to see if finished draining, if so slide under the truck and wipe the hole then reinstall the sump bolt, tighten to specified torque setting or you can usually judge it yourself, DO NOT OVER TIGHTEN.
12) Now get your new oil and fill her up with how much is recomended in your hand book, mine was 4.5ltrs, remember you already filled the oilfilter with oil.
13) once you have put the amount in, slide the sip stick in and remove it again check the end for how far the oil comes up the stick there will be a low level and full level on the stick. If on the low level add more oil, if on the full level replace the stick.
14) put oil cap on and check underneath for leaks, then if all clear start your engine.
15) let it tick over for a min or two then shut her off, and check dip stick add oil if need be.
16) If all ok dip stick reads right engine sounds right and no leaks Congratulations you just done a oil change.
